1 Peter 1:24-25
"For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the Word of the LORD endureth for ever. And this is the Word which by the Gospel is preached unto you."
So why does Peter say that all flesh is as grass? Because as a regenerated believer, you learn that this flesh doesn't get any better or any stronger. The more you learn of Christ, the more you see the futility of any work of this wicked flesh.
This flesh will perish but those that Christ redeemed on the cross at Calvary are upheld in Him, "The LORD upholdeth all that fall, and raiseth up all those that be bowed down." (Psalm 145:14) The more we are taught of Christ by His Spirit, of His righteousness, of His perfection, of His finished work, in contrast to our sinfulness, the lower we bow to Christ as the Only True Glory.
"And this is the Word which by the Gospel is preached unto you." Our inward man is renewed by the preaching of His Word, because in Christ, the Word of God, is everlasting life, while in our flesh, there is only a withering away, a falling apart, until it perishes, "...though our outward man perish, yet the inward man is renewed day by day." (2 Corinthians 4:16)
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, Will of God." (Romans 12:2) The good, acceptable, and perfect Will of God is His Son, our LORD Jesus Christ and His finished work on this earth.
"For the LORD Himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the LORD in the air: and so shall we ever be with the LORD. Wherefore comfort one another with these Words:" (1 Thessalonians 4:16-18).
Very comforting and glad to hear that, for sure Christ is revealed in the scriptures.
